Sea Foam?

[dcmaynard]

I have a 96 EB with 118000 mile on it. My brother told me to use sea foam on it. but he could not really tell me much about it, he just said that it cleans your engine. So my question is should I use this stuff and do it put it in the gas tank or the oil? he said that it could be used in either place.
Thanks

He's right, it can be used in either place. I've used it to de-carbon engines before and was impressed with how well it worked. All the instructions for use are on the can. Where you put it depends on what you are trying to accomplish, cleaning the fuel system, cleaning the oiling system, or de-carboning the upper half of the engine.

ok that sounds good. Would it be safe to put it in all 3 places at one?

[shorod]

I suppose, but then you won't know which made the largest improvement.

Be sure to read the instructions on the can, you won't necessarily use the entire can for each application.

I heard that u should not use SEA FOAM on a explorer, somthing about the carburator or the way the air intake or something like that is set up.

[dcmaynard]

I have heard that before. Has anyone else heard that I should not use Sea Foam? I dont have a Carb.

I suspect that what they are referring to is the coated intake plenum, and the fear that Sea Foam, or any throttle body cleaner, will dissolve the coating that was applied at the facotry.

If you add the Sea Foam to the fuel tank or to the crankcase, it is not going to contact the intake plenum in full strength (a little from the crankcase could make it to the intake via the PCV valve) so that shouldn't be a concern.

The coating applied at the factory is intended to prevent a build up of carbon and sludge in the intake. My personal take on this is that if there is a build up on the intake plenum/throttle body that requires something such as Sea Foam as a decarbonizer or throttle body cleaner, then the special coating is no longer doing its job anyway. Plus, many throttle body cleaners sold these days claim to be safe for coated throttle bodies.
